扶余/松原-肇东断裂研究综述

Research Status of Fuyu/Songyuan-Zhaodong Fault

扶余/松原-肇东断裂是松辽盆地内一条重要隐伏断裂,因以往记录到的中强地震较少而缺少对其的研究。近年来该断裂地震活动明显增强,是目前东北地震区地震活动最为强烈的断裂构造,故对断裂活动性研究十分迫切。在掌握了石油深部资料后,通过收集总结断裂相关的地质构造背景、地震记录、地球物理场特征以及地球物理探测资料等,以产状、地震活动性,最新活动年代为依据将断裂分为四段,综述了各分段断裂产状、性质、活动历史及活动年代等,并对断裂下一步研究提出建议。

As an important concealed fault in Songliao Basin, the research of the Fuyu/Songyuan-Zhaodong Fault is little due to few recorded moderate seismic activities. But in recent years, the prominently intensifying seismic activities of this fault have made it a fault with most intense seismicity in Northeast seismic region, thus necessitating an urgent study on this fault＇ s activities. After collecting the in-depth petroleum data, by collecting and summarizing the fault-related research status of geological structure background, seismic records, geophysical field anomalies, geophysical detection data etc. , the fault is divided into four segments on the basis of its occurrence , seismicity, and the latest active age. Then this paper reviews the occurrence, nature, activity history and active age of each fault segment. Finally, some suggestions for further research on the fauh are put forward.
